Monobloc tap fails to pass water after brief disconnect.

[finadvis]

Newbie from Canada is puzzled why on recconnecting, my bathroom sink monobloc taps fail to pass any water after whole unit was unbolted from wall mount to do some new tiling . Whilst the sink was in the workshop my wife gave it a good clean so may have had whole unit upside down; could this have jammed a oneway/non return valve???????
There is full H & C pressure at the stop valves at wall.

If you removed a non return valve are you sure you put it back the right way?
Is it possible that some foreign matter has entered the valve?
Did she take the thing to bits when she cleaned it and not put it together properly?

It's not usual for us to comment on stuff outside of the UK as we are generally not familiar with it.

PS I am not in Pakistan I just like the pretty flag and can smell curry

Thanks for response; luckily the plumbing angels had worked their magic during the night and the taps were working fine this morning. No idea why, perhaps they just needed a rest. Anyway thanks again for a great forum.
